I’m not sure of the paring or if there even was a paring. Here’s what I remember.
The team are having some kind of movie night. I believe that Phil is there. It time to chose a movie and Clint asks for something to be omitted and Tony makes fun of him for it. It might of been water. Tony makes a sarcastic comment about Clint being afraid and saying that his torture was worse. Or something like that. Clint then in explicit detail tells the team about the time he got waterboarded. The team is completely silent during his story.
That’s all I can remember.
